Terms of Service

1. Acceptance of Terms and Eligibility

A. Acceptance

By downloading, building, installing, or connecting to MNDO software, accessing the website at mndo.online, or utilizing associated relay services, you enter into a legally binding agreement governed by these Terms. If you do not agree to these Terms in their entirety, you must immediately discontinue use of MNDO software and delete the application.

B. Eligibility

You must be at least 13 years of age (or the minimum legal age of digital consent in your jurisdiction) and possess the legal capacity to enter into binding agreements. You represent that your use of MNDO does not violate any applicable local, national, or international law, sanction, or regulation.

2. Cryptographic Identity Architecture

MNDO does not operate traditional user accounts. Understanding this distinction is foundational.

Unlike conventional messaging platforms that assign you a database record tied to a phone number or email address, MNDO generates an asymmetric cryptographic keypair (Ed25519 / Curve25519) directly on your device. Your identity is defined mathematically by your public key.

• You own and custody your private signing keys and ratchet state.
• No MNDO server has administrative access to modify, revoke, or reassign your keys.
• Account recovery relies exclusively on your 12-word seed phrase or local device backups.

3. Classification of User Content & Metadata

Review the precise technical status of data transmitted or stored across MNDO. The following categories apply:

• Private messages — end-to-end encrypted via Signal Double Ratchet. Content is never visible to relays or MNDO infrastructure.
• Public metadata — profile display names, relay lists, and public key identifiers are published to the Nostr protocol and are visible to any relay operator or network participant.
• Local storage — encrypted at rest via SQLCipher (AES-256) on your device. Accessible only with your device credentials.
• Connection metadata — IP addresses and timestamps are visible to relay operators you connect to but are not collected or stored by MNDO.

4. User Content and Public Broadcasts

Ownership & Limited License

You retain all intellectual property rights and ownership in the content you create. By transmitting content through MNDO, you grant MNDO the strictly limited, non-exclusive technical license necessary to route, relay, and display that content as instructed by your client.

Public Broadcast Disclaimer

Content marked as public (posts, reactions, profile metadata) is published to the open Nostr protocol. Independent relay operators and users may mirror, cache, and archive this data. MNDO cannot enforce deletion across third-party network nodes once published.

5. Acceptable Use Policy

You agree to use MNDO responsibly. The following activities are strictly prohibited:

• Unlawful activity — engaging in or facilitating illegal acts, terror financing, or severe harm under applicable law.
• Malware & exploits — distributing viruses, trojans, ransomware, or attempting unauthorized access to relays or devices.
• Spam & Sybil flooding — automated event spamming, relay resource exhaustion, denial-of-service, or network disruption.
• Credential theft — phishing, social engineering, key theft, or intercepting seed phrases of third parties.
• Harassment & threats — defamatory speech, targeted threats of violence, extortion, or non-consensual tracking.
• Infrastructure sabotage — exploiting relay vulnerabilities to disrupt communications for legitimate network participants.

6. End-to-End Encryption Does Not Excuse Unlawful Conduct

MNDO implements Signal Double Ratchet end-to-end encryption for private messaging. Because the cryptography prevents MNDO maintainers, relay operators, and network intermediaries from inspecting private message plaintext, you bear sole legal and moral responsibility for all communications, files, and media you transmit.

Encryption is a privacy tool, not a shield against legal liability. Misusing cryptographic tools for criminal enterprises remains punishable under applicable law.

7. Limits of Decentralized Infrastructure

Because MNDO does not own or control the global Nostr network, specific operational guarantees cannot be made. MNDO expressly disclaims guarantees regarding external network conditions. Specifically, MNDO cannot guarantee that:

• Every relay you connect to remains online or responsive.
• Every message envelope is delivered without latency.
• Relays will preserve message history permanently.
• Deletion requests will be respected by all third-party relays.
• Custom third-party Nostr clients adhere to MNDO protocol conventions.
• Network connections will be immune from local ISP disruptions.

8. Scope of Infrastructure Access Restriction

In a centralized app, administrators can "delete your account" or "ban your identity from the protocol." In MNDO, we cannot confiscate your cryptographic keypair or ban your identity from the decentralized Nostr network.

However, MNDO maintains absolute authority to restrict, suspend, or terminate an identity's access to:

• Official MNDO-hosted relay infrastructure.
• Official MNDO prekey directory and discovery endpoints.
• MNDO-operated Blossom media storage nodes.
• Official MNDO push notification gateway infrastructure.

9. Software License and Brand Guidelines

AGPLv3 Open Source License

The MNDO client codebase is licensed under the GNU Affero General Public License v3.0 (AGPLv3). You are free to inspect, audit, modify, and distribute the code under the condition that derivative works preserve the same license and publish their source code.

Branding & Trademarks

The MNDO name, logo, iconography, and original site documentation are proprietary marks of the project maintainer. The AGPLv3 license does not grant permission to use MNDO trademarks for commercial branding without written consent.

10. Responsible Disclosure and Vulnerability Guidelines

We welcome security researchers who examine MNDO's cryptographic implementations in good faith. If you identify a vulnerability, report it privately to risvandev@gmail.com before any public disclosure. We will work with you to verify and patch the issue promptly. Malicious exploitation of vulnerabilities against live users or infrastructure will be reported to appropriate law enforcement authorities.

11. Disclaimers of Warranties and Limitation of Liability

Disclaimer of Warranties ("As-Is")

WE DO NOT WARRANT THAT THE SOFTWARE WILL BE UNINTERRUPTED, BUG-FREE, IMMUNE FROM MALICIOUS ACTORS, OR THAT MESSAGES WILL ALWAYS BE DELIVERED TIMELY.

12. Jurisdiction and Applicable Legal Venue

These Terms and any dispute arising from or related to MNDO shall be governed by and construed in accordance with the laws of the Republic of India, without regard to conflict of law principles. You agree that any legal action or proceeding shall be subject to the exclusive jurisdiction of the competent courts in Ernakulam / Kochi, Kerala, India.

13. Modifications to Terms

We reserve the right to amend these Terms at any time. Changes will be reflected with an updated "Last Updated" timestamp and committed to our GitHub repository. Continued use of MNDO after such modifications constitutes your acceptance of the updated Terms.
